+### Normalizes
+
+`YAAF` form objects support `normalizes` the same way as `ActiveModel` models. For example:
+
+```ruby
+class RegistrationForm < YAAF::Form
+  normalizes :email, with: ->(email) { email.strip.downcase }
+  normalizes :name, with: ->(name) { name.strip.titleize }
+
+  # ...
+end

 ## Sample app
 
 You can find a sample app making use of the gem [here](https://yaaf-examples.herokuapp.com). Its code is also open source, and you can find it [here](https://github.com/rootstrap/yaaf-examples).
